How secure is My Recheck?

My Re Check utilizes end-to-end cryptography, protocol for anonymisation and masking, along with digital proofs to guarantee maximum privacy in sharing data. Blockchain architecture provides an immutable environment to ensure that digital proofs cannot be altered or deleted. My ReCheck preserves the perfect balance between security, privacy and traceability. Transactions are recorded in a way that only users who did them can verify them using their identities.
